IMPROVEMENT IN ELV-TRAPS.

Specification forming part of Letters Patent No. 129,763, dated July 23, 1872. y

` Specification describing a new and Improved Fly-Trap, invented by FRIEDERIC STENGEL, of the city, county, and State of New York.

The drawing represents a vertical .central section of my improved {1y-trap.

This invention relates to a new ily-trap, which is open at the bottom and closed on top to enable the ies to enter from below, but prevent them, owing to their peculiar habit of. not ilying downward in asmall chamber, from escaping when once they have entered.

A in the drawing represents the body of the ily-trapfmade of glass, with legs or supports a a, whereby its bottom is raised aboverthe supporting table or article.l The' bottom b of the trap is made perforated, and, by preference,

slightly conical, as shown. The top of the trap A is closed by a stopple or plate, d, or by any other suitable means.

The glassbody A may be made in suitable form, longer or wider in proportionthan shown, and may have the legs a formed on it of glass or on a separate supporting-frame, B.

In using the trap it is placed on a table or support and closed on top, and sugar or other matter attractive to thejiies is put on the table under the trap, directly below the opening in the bottom 11. The ilies collected-on such attractive substance will, on every disturbance, fly upward and enter the trap, whence, for the reason above stated, they do not escape. It will onlybe necessary to wave the hand toward the trap or otherwise disturb the flies under it to cause their entry into the trap.

Having thus 'described my invention', I claim as new and desire to secure by Letters Patent- The fly-trap composed of transparent glass body A having supportswt a, the conical per- .forated bottom b, and the stopple d, constructed and put together as described.
